if all goes well for Liverpool I think they can finish in the Champions League Zone next season.
I think they will do better than just merely qualify for the CL, i think Liverpool is going to be back in the picture to compete with Manchester City for the EPL title, Klopp has ample time to study his team and recruit the players he needs, and that is what they are doing already. Liverpool are not playing the in CL next season, thus they can fully concentrate on the EPL and give City a good fight. Next EPL season will be so interesting, City are going for their fourth consecutive EPL title, and all the teams will be out to stop them, it'd be so competitive.
In the coming season I also think that clubs like Man utd, Newcastle, Arsenal and of course Liverpool will compete very fiercely not to let Man City win the EPL title again. And Jurgen Klopp is currently really serious about increasing the strength of the team. especially for midfield. Liverpool have brought in 2 new midfielders. and one of them is Mac Allister whose performance was indeed extraordinary last season while playing for Brighton. So I think Liverpool will really be stronger in the coming season.
